This bowl cozy set is perfect for kids and for adults as well ☺️. No more “too hot” or “so cold”. They are made for microwave usage, but can also be used as a serving pad. They are reversible! You will find lots of uses for this adorable cozy set which is great for everyday usage especially for fall. They are made with 100% cotton fabric, thread, and WrapNZap batting. The cozy’s have double thickness batting and are great for microwave usage. These cozy’s are great for reheating food! WrapNZap instructs you to do 2 minutes at a time, no more than a total of 8 minutes on a rotating base . If you must reheat for longer, please reheat without the cozy and then add the cozy toward the end of reheating. The cozy is meant for reheating only, not for cooking!! These bowl cozys are also great for keeping you hands comfortable with cold items, like ice cream!! The large cozy has approximately 10” dia top with a 6” dia bottom and 3.5” high. Plenty of room for larger serving bowls or to display any food item. The medium cozy has approximately a 8.5” dia top with a 5” dia bottom and 2” high. Perfect for soup bowls!
